Heretotor'e it has been customary to erect towers piece by piece. rThis has necessitated a laborious and tedious assembly ot the separate pieces of the towen This procedure was also` dangeroust-o the .workman employed thereat. in towers of the type referred to there are provided opposed rails upon which an elevator may be vertically. reciprocated7 the elevator serving to carry buckets of concrete up into the tower to a suitable device troni which the concrete' is ied from a chute to various parts ofthe structure upon which the concrete is to be The elevators are also usedA for moving brick and other materialsl to various tloors of the building under construction.

My invention is concerned with means for erecting the tower in which` the elevator may be reciprocated, Thetower may be `briefly described as. comprising a pair ot sides. 6 andf having their opposite .ends

tied. upon one.. anotheriby any..suitable I means such as cross bars whereby toetfect a substantially hollow rectangular structure centrally within which 1s a yert1- caliway or elevator4 shaft-,through which the 1 elevator be reciprocated. The sides the base carry a plate 2O in which vided an aperture 21 tor vis preferably used as a shaft. provided at .limiting the .the `aperture Y21. Theaperture 1s-madesuf cornprise angie iron structures each about siX I'eet by twenty 'feet that are bolted one upon another in a vertical relation, and the sections 8 on the side 6 are secured to the sections on the side 7 by the cross ties or bars as shown at 35 and as previously stated. Heretofore the various pieces comprising any one section such as 8 were assembled one upon the. other as the tower was built upward. 1When employing device embodying my inventionithe sections such as S'are assembled upon the ground and are hoistedto position and are secured upon the adjacent vertical sections and upon the yhorizontally opposed sections.

vFrom the foregoing it will be understood that ai'ter Vtwo sections 8 have been raised to a given position and have been secured upon the sections 8 next below said position, -workmen will secure the horizontally opposed sections by suitable `cross bars, this being the only assembly work done by the workman.

`In order to erect the assembled sections 8 there is provided a hoist 9 that may be reciprocated vertically of `the tower. Each tower is provided with rails, generally in the form of channel irons 10 that serve as guides or runways for-an elevator in the completed tower. The hoist 9 comprises a base 11 and a top,12, both of which are substantially identical instructure. Each of these elements comprises a pair ci' angle irons 13 and 14 that are secured in spaced relation by any suitable means such as the channel irons 15 and 16. The channels 15 and 16 are spaced at a distance from the ends of the angle irons 134 andlli so that ways 17 and 18 are provided at the ends of the said structures in which thefrails 10 of the tower may be received. The rails are mounted upon the walls or sideseof the tower in any suitable manner suchas by means of angle brackets 19.` The angle irons 13 and 14 comprising is prothe reception of the lower end of a shaft 22. A hollow pipe The shaft is itslower-end-with a` collar 23 for movement of the .shaft -.through icien-tly large .to-,allow afslight Alateral movementof thelower endroit` the shaftinrelatioirtoV the plate.` Staples or hooks 24:, are

...carried by" the `1-ilate20, for ,providingA means whereby the hoisting device may be raised or' Cil lowered in the tower. The angle irons 13 and 14 are provided with apertures 25 adjacent their outer ends for the reception of bolts 26 that may engage the angle brackets 19 and are used to position the hoisting structure at various elevations in the tower. The channels 15 and 16 extend between the base 11 and the top 12 for retainingl the top and base in a :fixed and rigid relationship. rlhe angle irons 88 and 34 comprising the rop have formed in them apertures 27 and 28 as shown in Fig. 5, the apertures being adapted to receive bolts 29 for retaining the upper end of the shaft 22 in a central position. The bolts 29 may be removed whereby to permit positioning` or inclining of the shaft 22 so as to dispose the upper end of the shaft 22 outwardly beyond the tower. Additional apertures such as 27 and 28 may be provided in the angle irons at the top for retaining the shaft in such inclined positions. The inclination of the shaft is made possible because the aperture 21 in the base plate 2O is made sufficiently large to permit such relative movement of the shaft and the angle irons comprising the top and base. The shaft 22 may be made in sections that may be detachably mounted upon one another by any suitable means such as the sleeve elements 30 and suitable fastening means such as bolts 31. Suitable means may be provided at the upper end of the shaft. such as the pulleys 32 for hoisting the section 8 of the tower to various positions.

In operation, the hoisting device is positioned at the place where the tower is to be built, suitable means such as cables being employed for temporarily holding the hoisting devices in a determined position. The lower sections 8 of the tower are then assembled about the base of the hoisting device, the guides or track 10 of the tower being so positioned that they are disposed within the ways 17 and 18 formed at the outer ends of the base and top of the hoisting device. It is preferable to build up a number of sections 8 about the hoisting device to such height that the top 12 will be supported by the tracks 10 of the tower. Thereupon additional sections 8 may be hoisted by means of the pulleys 32 and suitable tackle 37, and may be held in proper position until the workmen can secure an assembled section 8 on one side of the tower to a similar assembled section 8 on the opposite side of the tower. After a number of sections 8 have been built up to such height that the upper end of the tower is substantially of the height of the shaft 22, suitable block and tackle may be mounted upon the tower, for example as shown at 38. and one end of the rope of such tackle may be secured to one of the bolts or staples 24 for raising the hoisting device within the tower. The hoisting device will be raised to such extent that ad.

ditional sections 8 can be brought into position by means of the hoist-ing device, whereupon the bolts 26 will be inserted through the apertures 25 in the base, and the engagement of the bolts 25 upon the angle brackets supporting the tracks 10 will position the hoisting device within the tower. This procedure may be continued until the tower has reached the desired height.

When employing a hoisting device as shown herein the sections 8 may be assembled upon the ground, with no danger to the men assembling same whereupon the assembled sections may be hoisted in position by a steam engine or the like and may then be secured by workmen upon the tower. A number of the sections, when assembled provide a structure upon which additional sections are secured whereby to build upwardly or erect a tower that is to be used for carrying various materials to the various floors of a building to be constructed. It will therefore be evident that the device disclosed herein is for use with a tower undergoing erection or being dismantled, and that in operation a portion of the applicants device extends upwardly from the tower section upon which the device disclosed herein is mounted, for hoisting additional tower sections to position.

After the tower has been constructed to the desired height the hoisting device is lowered within the elevator shaft or way within the tower and disassembled at the bottom of suoli way, whereupon the elevator may be assembled within the way for receiving concrete, brick or the like within the tower. After a tower has served its purpose, it may be taken down by employing the same hoisting mechanism to lower the various members of the tower.

What I claim is:

1. The combination with a tower having a vertical central way and vertical tracks within the way, of a hoisting device comprising a top and a bottom, means for spacedly securing` the top and the bottom, the top and bottom being provided with ways for the reception of the tracks of the tower, a shaft-supported by the top and the bottom and extending upwardly beyond the top for projection above the tower and means carried by the upper end of the shaft for raising and lowering tower sections.

2. The combination with a tower having a vertical central way and vertical tracks within the way, of a hoisting device comprising a top and a bottom, means for spacedly securing the top and the bottom, the top and bottom being provided with ways for the reception of the tracks of the tower, a shaft supported by the top and the bottom and extending upwardly beyond the top for projection above the tower, means carried by the upper end of the ,Shaft for raising and lowering tower sections, and means for adjustably inclining the shaft in relation to the top and the bottom of the hoisting device.
